SPECIFICATION forming part of Letters Patent No. 624,169, dated May 2, 1899.

Be it known that I, LOUIS MICHEL BUL- LIER, of the city of Paris, France, have invented a new and Improved Burner for Lighting by Acetylene Gas and other I-Iighly-Carbureted Gases, (for which I have obtained Letters Patent in France for fifteen years, dated April 20, 1895, No. 246,768, and in Belgium for fteen years, dated April 20, 1895, No. 115,l61,) of which the followingisafull, clear, and exact description.

My invention has for its object to produce a new and improved lighting-burner in which inlet gas-ducts are combined with air-sucking ducts in order to obtain a thorough combustion of acetylene and generally of any highlycarbureted gases used for lighting purposes.

In order to make my said invention clearly understood,I will proceed to describe the same with reference to the annexed drawings, in which- Figure 1 shows an enlarged sectional elevation of a burner made according to my invention. Fig. 2 shows inelevation ab urner which is not liable to be choked by a deposit of carbon, which often occurs in acetylene burners; and Fig. 3 is a modified form of a burner of the same character.

In Fig. l I have shown au element of my burner in which gas is admitted through a' duct d. Into this duct an air-'inlet Z) opens, so that air is sucked into the burner by the current of gas and ejected from the burner comlningled with gas. The mixture of air and gas is thus obtained Within the burner, passes to the outlet of the burner, and may be easily lighted, and the thorough combustion of acetylene and other gases is so obtained, while the lighting power of the ame is increased.

In order to avoid an objectionable deposit of carbon, I preferably construct my improved burners as shown in Figs. 2 and 3. According to this improvement two or more burners are placed at an angle to each other so that the liames meet and become attened one against the other, so that the resulting flame is somewhat similar to the flame of a Manchester burner.

ing part of the flame is placed far from the ducts of the burner on account of the excess By these means the lightof 'air introduced by the lateral air-passages. This excess of air insures a thorough combustion of the gas in the space between the oriices of the burners and the meeting of the flames; but as the iiames burn blue at the outlet of the burners all deposit of carbon is avoided.

Any number of small air-inlets h may be Vused--as,for instance,as shown dotted in Figs.

limit myself to the form of burner shown,

but that other forms may be used without departing from the spirit of my invention.

I wish also to specify that the shape and size of the different parts o f my burners may be varied and that any convenient materials may be used for the construction of the same.

What I claim, and desire to secure by Letters Patent,lisv In an apparatus for burning acetylene, the combination of a plurality of burners, each comprising an air-passage, a gas-passage so arranged with respect to the air-passage as to produce a suction of air therethrough, with means for commingling the air and gas Within the burner and for passing the elements thus commingled to the burning-point of the burner, the said burners being set to deliver their commingled streams of air and gas toa common burnin g-point, where they will meet, substantially as described. Y

The foregoing specification of my new and improved burner for lighting by acetylene gas and other highly-carbureted gases signed by me this 17th day of December, 1897.
